acute diarrhea in horses of the potomac river area: examination for clostridial toxins.	fecal specimens from horses in montgomery county, md, and in fairfax and loudoun counties, va, were examined for clostridium perfringens type a enterotoxin and for c difficile cytotoxin (92 and 108 specimens, respectively). the toxins were found in feces from horses that had experienced an acute diarrhea syndrome and from clinically normal horses. the toxins did not appear to be primary determinants of the diarrhea syndrome, although they may have contributed to the spectrum of clinical entities ...	1984	6469842
rapidly measured indicators of recreational water quality and swimming-associated illness at marine beaches: a prospective cohort study.	in the united states and elsewhere, recreational water quality is monitored for fecal indicator bacteria to help prevent swimming-associated illnesses. standard methods to measure these bacteria take at least 24 hours to obtain results. molecular approaches such as quantitative polymerase chain reaction (qpcr) can estimate these bacteria faster, in under 3 hours. previously, we demonstrated that measurements of the fecal indicator bacteria enterococcus using qpcr were associated with gastrointes ...	2010	21040526
low prevalence of netb and tpel in historical clostridium perfringens isolates from broiler farms in alabama.	the discovery of novel clostridium perfringens toxins netb and tpel has initiated questions regarding their role in the pathogenesis of disease. however, data showing the prevalence of these genes in c. perfringens populations are limited to certain geographical areas. if netb and tpel are important virulence factors for disease worldwide, one would expect to find these genes in isolates from other regions as well. to address this hypothesis, c. perfringens isolates collected from alabama broile ...	2015	26292533
